Abstract: 
Ongoing experiments at JLAB investigate the nuclear transparency in exclusive rho(0)(770) electroproduction off nuclei. In this work we present transport model predictions for the attenuation of rho(0)s in nuclei and for color transparency (CT) effects as observable at CLAS with a 5 GeV electron beam energy. A full event simulation developed here permits to study the impact of actual experimental acceptance conditions and kinematical cuts. The exclusive (e, e' rho(0)) cross section off nucleons is described by diffractive and color string breaking mechanisms extended toward the onset of the deep inelastic regime. Different hadronization and CT scenarios are compared. We show that a detailed analysis of the elementary cross section, nuclear effects, and experimental cuts is needed to reveal the early onset of rho-CT at present JLAB energies.
